This paper presents In situ quick repairing of defects inside a telescoping multi-walled carbon nanotubes (MWCNTs) using contact resistance. The defects were inserted and repaired by In situ nanomanipulation technique inside a transmission electron microscope (TEM). The defects were quickly (less than ∼0.1 s) repaired by applying a current after contact with electrode. The repairing of defects was...
This article presents a preliminary results on the development of a compact FE-SEM equipped with a multiwall carbon nanotube field emission cathode, a Butler electrostatic lens as a condenser lens and an objective lens made of a permanent magnet. The instrument was tested on a Cu 200 mesh with 25 mum line width
The growth characteristics, such as temperature and pressure dependence, of carbon nanotubes (CNTs) by alcohol catalytic CVD (ACCVD) were studied. The thickness of the CNT layer is examined using scanning electron microscopy It was confirmed that the growth temperature could be lowered to as low as 400degC. This result indicates that the ACCVD technique is suitable for the low temperature CNT-FEA...
